Security Clearances

Heurlin Sherlock regularly represents employees in Arizona regarding federal security clearance applications and revocation hearings.

Tucson is home to Raytheon Missile Systems, and a high percentage of new jobs in the Tucson region each year are in the aerospace and defense / homeland security industry. Tucson has been ranked in the Top 10 metro areas for aerospace / defense manufacturing by Business Facilities magazine. These employment opportunities place a premium on employees being able to obtain and hold a security clearance as a condition of their job.

Having a security clearance is a privilege and a sign of trust. A security clearance demonstrates that you are willing and able to safeguard information related to national security. Many federal employees, members of the military, government contractors, and certain private sector employees, are required to hold security clearances because their jobs require access to classified documents or secure facilities.

Applying for a security clearance includes an extensive and thorough background investigation, where anything from overseas travel to credit card debt can be taken into consideration. Even if you have been granted a security clearance, that clearance may be taken away at any time. Because denial or revocation of a clearance means the loss of your job and income, a security clearance application must be prepared with care and skill.

Our experienced attorneys regularly assist applicants in all stages of the security clearance application process, including:


  • Top Secret
  • Sensitive Compartmentalized Information (SCI)
  • Special Access Program (SAP)

Our lawyers provide counsel through the entire application, revocation, and appeal process, such as:

  • SF-86 security clearance applications and other pre-clearance requirements.
  • Preparation for background investigations and formal interviews by Defense Security Services (DSS) or Office of Personnel Management (OPM).
  • Evaluation based on adjudicative guidelines.
  • Responding to the Statement of Reasons (“SOR”).
  • Demanding a hearing and advocating at a hearing.
  • Representation at post-denial hearings with the Defense Office of Hearing and Appeals (DOHA), Department of Defense, FBI, CIA, and all federal courts and government agencies, including document and witness preparation.
  • Preparation and representation throughout appeal, if necessary.

If you have recently had your application for security denied or your clearance revoked, or are applying for a security clearance, contact the attorneys at Heurlin Sherlock today.
